Abstract
The invention concerns a bearing mounting for rotating shafts, in which the main bearings are roller bearings and the shafts turn at more than ca. 3000 r.p.m. With the aid of auxiliary bearings, these main bearings are loaded radially according to the invention in order to prevent the rollers and roller cages of the main bearings from rotating with only a reduced r.p.m. in the case of nonloaded rotating shaft and being suddenly accelerated with a sudden loading of the shaft and thus wearing prematurely. This radial load results from the fact that the auxiliary bearings are maintained eccentrically shifted.
